11x

11x is an algebraic expression representing the product of the integer 11 and the variable x. It is a linear term in x with coefficient 11. In standard notation, 11x is read as “eleven times x” and is equivalent to adding x to itself eleven times when x is a real number, or multiplying the scalar 11 by x.

As a function, the expression can be written as f(x) = 11x. This defines a linear function with

In equation form, 11x is used to relate x to another quantity. For example, if 11x = y,

11x is also classified as a monomial of degree 1 and appears as a basic building block
